Hi,

I'm glad I was able to help you!

After testing it, could you confirm that it works correctly? This way, if others have the same question, they will have a verified answer.

Thank you!

Best regards,

Thank you Simon for your detailed response! I do have an old J-Link EDU version, probably needs an update. Since it supports openOCD via USB for debugging, I could try that, even if it means that I wouldn't be able to use it directly from within the extension.

Hi,

The VS Code extension only shows device are connected via J-Link. The XIAO nRF54L15 has the pins needed to be connected to a J-Link but does not have an on-board J-Link.

However, if you open a nRF Terminal and type the flashing command manually (west flash), it should be working. I think it will use openOCD under the hood.

You can see here the compatibility matrix for programming and debugging this module.

If you have a J-Link controller or a Nordic DK (through the "DEBUG OUT" connector) you might also be able to use it to connect to the J-Link interface of your XIAO nRF54L15 module.

If you don't have a J-link controller lying around, I believe you should also be able to program it through the USB using nRF Util.

I hope I was able to help you. If you have any more questions, feel free to ask.

Best regards,
